Cylinder creates a tube specified as a radius around a center line of the appropriate length. You can specify the length of the cylinder either by begin and end points or by specifying a center point, a direction, length and radius. It has no caps on the ends so you may need to use a Cap surface to complete your design. Cylinders are exact surfaces and contain a seam where two edge boundaries meet. Be careful not to trim across the seam. Editing along the seam is fine.
Follow these steps to build a cylinder:
A cylinder requires no curves or geometry for input.
Use the Surface wizard or select Cylinder from the surface toolbar flyout.
Name the surface for future reference.
Pick the construction method.
Two points
Enter the coordinates for the center point, or click Pick and pick the point with the mouse.
Enter the coordinates for the end point, or click Pick and pick the point with the mouse.
Enter the radius of the cylinder.
Direction, length
Enter the Length of the cylinder.
Enter the Center point coordinates of the cylinder.
Enter the Direction coordinates.
Enter the Radius of the cylinder.
Click Finish or OK to create the surface.
